An Article 2011 of Eastern Africa was explained a few things and overlooked in terms of its hydrocarbon potential for many years, is increasingly viewed as an exploration hot spot, with recent discoveries in the Albertine Rift and offshore Tanzania leading to resurgence in interest. Dominated by the East Africa Rift System (EARS), the region has a complex geological history and provides the potential to bring together modern techniques to aid geological understanding and to help efficiently target hydrocarbon exploration.
It turns out that the Somali Plate – which has a fault line stretching from the East African Rift southwards down through South Africa and exiting through Durban – is slowly breaking away…and will one day form a new continent separate from the rest of Africa!

African Continent is Breaking Apart & New Ocean Is About to FLOOD Over the Afar Region!
Astrium has recently completed an ambitious project to interpret the complete EARS, an area of approximately four and a half million square kilometres, at a scale of between 1:100,000 to 1:500,000. The project incorporates a broad range of territories including, from north to south; Eritrea, Djibouti, Somaliland, Eastern Ethiopia, south-east Sudan, Uganda, Kenya, Rwanda, Burundi, eastern border area of Democratic Republic of Congo, Tanzania, Malawi, Mozambique, and the border zones of Zambia, Swaziland and South Africa.
The EARS is an active continental rift zone with an elongate morphology, extending approximately 5,000km from the triple plate junction of the Afar Triangle in Ethiopia to the Inhambane region in Mozambique. Dominated by extensional faulting, the area is characterised by two main rifting trends, defined as the Eastern and Western Branches, with several phases of superimposed rifting having occurred.
When studied in detail, the full complexity of the rift system becomes clear. As well as the main rift structure, smaller grabens are also apparent, running parallel or branching from the main rift feature. The orientations of the rift basin and grabens are controlled by the tectonic regimes the region has experienced since the Late Permian. By far the most significant control on the current rift morphology is the Tertiary to Quaternary rifting, manifested in the general north-south orientation of the rift structure. This dominant trend truncates structures formed during previous rifting events, namely the Late Permian to Early Jurassic ‘Karoo’ events and the Cretaceous event. Karoo rift basins are concentrated in the south of the EARS, predominantly in Mozambique and Tanzania, and include the north-north-east trending Luangwa rift and the Selous graben, trending north-east to south-west.
The Eastern Branch of the Rift runs from the Afar Triangle triple junction in Ethiopia and Eritrea to the South Tanzania Divergence where the rift meets the Tanzania Craton. In the north, the eastern rift trends north-east to south-west, then north-north-east to south-south-west at the Ethiopia-Kenya border, before deflecting north-south at Lake Baringo. A series of small rifts branch off from the main structure at Lake Turkana, before terminating directly north in southern Ethiopia. A number of oil slicks have been identified on Lake Turkana and there have also been reports of good quality source and reservoir rocks in the adjacent Lokichar and Kerio Basins.
The Western Rift stretches from the border between Uganda and Sudan in the north, to the major rifts of Lake Tanganyika and Lake Nyasa (Malawi) – predominantly trending north-south except where it diverts around the Tanzanian Craton near Lake Tanganyika. The extensive lakes in the Western Branch, including Lakes Albert, Edward, Nyasa (Malawi) and Tanganyika, have a significant number of oil seeps identified from Radar imagery, with the potential for associated good quality source rocks.
In the southern section of the Western Rift, the surface expressions of geological features are dominated by the Tertiary-Quaternary fracture sets associated with the EARS. These mostly trend approximately north-south and cut the older, failed north-east, east-west and north-west trending rifts of the Permo-Triassic Karoo grabens, as well as the multi-temporal, multi-directional tectonic elements of the Precambrian Basement. The intracratonic basins containing the Karoo Supergroup are distinct features on the remote sensing imagery, and can be accurately defined. Further south, the Inhembane area of Southern Mozambique is transacted for over 300 km by Quaternary north-south intersecting narrow graben structures, 9-11 km wide, that are coaxial to the present-day coast and indicate that the extensional forces which formed the system are still active in this region.
The oil seeps identified by this study – in the rift lakes of Lake Tanganyika, Edward and Nyasa (Malawi) – may indicate the presence of a similar petroleum play involving the Tertiary sections, as discovered recently at Lake Albert. Additionally, for the lakes in the south, there is the potential for the seeps to be derived from older Karoo sediments common in the southern part of the EARS. Recent exploration on the Karoo basins such as the Ruhuhu and Upper Zambezi Grabens has revealed large reserves of Gondwana coals within the lower part of the Karoo Supergroup. These may yield commercial amounts of coal-bed methane as well as reasonable quality coals for future exploitation. Other prospective regions include the Ogaden Basin in Eastern Ethiopia. This is an area of proven hydrocarbon reserves with large gas discoveries and frequent oil shows from the Mesozoic
The Red Sea is formed when the Arabian plate diverge from the African plate. The divergence of the Nubian plate from the Somalian plate results in the flooding of the East African rift valley forming another sea or oceanic rift.
Die aardplate beweeg daagliks, en dis nie ‘n vreemde gesig om dit oral op alle kontinente waar te neem nie. Afar is boeiend en warm lawa wat uitstroom, aardplate wat beweeg en wat groot skeure veroorsaak. Lande sal letterlik op sommige plekke in twee geskeur word. Niemand weet regtig hoe voorspelbaar die aardplate kan wees nie en dalk heel anders daaruit sien. Dalk “voorspelbaar” maar nie heeltemal nie, heelwat stede het al onder water verdwyn.

A massive ‘ocean’ discovered towards Earth’s core (and perhaps more than one). When you read the Bible you will also find there were different floods which covered the whole earth. The different floods created by ONE, but there were also reasons behind those floods. There were also different waters, seas and oceans, formed and drained into their own places.
